The A7R IV is slightly beefier
than its predecessor, with a

Sensor
sensibility
The full-frame sensor
inside the A7R IV is a 35mm
Exmor R CMOS job, with a
Bionz X image processing
engine. Standard ISO range
goes from 100 to
32,000.
Found sounds
There’s an optional
ECM-B1M shotgun mic
(£340) that records a digital
audio signal and sends it
directly to the camera,
minimising noise and
distortion.
